Efficiency requirement
According to EU Regulation (EC) No. 640/2009, the IE3 efficiency requirement for low-voltage
motors with a power of 7.5 kW to 375 kW for line operation has been in force since January
01, 2015.
From January 1, 2017, the IE3 efficiency requirement for motors with a power of 0.75 kW to
375 kW applies for line operation.
Efficiency IE2 still applies for motors that are operated from a converter.
Please note the applicable country-specific rules and regulations.
Rotors
The rotor assembly is pressed onto the shaft together with the cage winding. The drive end of
the shaft usually has a cylindrical shaft end. Dependent on the design, a second shaft end
may be located at the non-drive end.
Cooling
The cooling system is designed as a closed, internal cooling circuit. The heat lost from the
machine is dissipated partially via heat conduction and partially via the cooling air at the cooling
water flowing through the cooling pipes. A shaft-mounted fan ensures circulation of the cooling
air.
